About this circuit
A simple 5 V DC source feeding a 1 k load resistor with the output measured by a voltage probe.
Circuit notes
DC Supply Load Reference
Application
Use this circuit as the simplest reference for powering a resistive load from a fixed DC supply.
Design Context
V1 provides 5 V across a 1 k load resistor referenced to ground. The voltage probe measures the supply rail directly, so the operating point table should report about 5 V.
Expected Behavior
The load node remains at the configured source voltage, and the resistor draws the corresponding DC current from the supply.
Key Values
- V1 is 5 V.
- RLOAD is 1 k.
- The simulation is a DC operating point.
Suggested Experiments
- Change V1 to another voltage and rerun the operating point.
- Change RLOAD to see how load current changes while the ideal source voltage remains fixed.
Featured Component
The DC voltage source provides a fixed voltage between its positive and negative terminals and is the basic supply element used throughout many CircuitSim examples.
